My partner and I purchased a Boremaster from Tim two years ago and would like to follow up on some of the comments made here on ebay about his rigs.  Tim provided the rig we purchased on time and complete, all of it.  Remember that inexperience is an issue when you drill your first well.  We have drilled two wells with our rig so far, and the only problems were related to us learning how to drill with this rig.  Our location is in north georgia and there are tons of rocks in this area.  Yes we had problems with these rocks until we purchased the proper rock drilling bits.  These bits are known as roller cone bits and are available with and without carbide tips.  Not only did we drill thru the rock we hit, but we did it with a six inch tungsten carbide insert bit that was much heavier and larger than we thought the rig would handle, but we were wrong as it did perfect.  One of the reviews here mentions certain difficulties they encountered and we want to address those who may have read these comments.  The following were complaint areas from another ebayer.  It's not our goal to insult anyone, imply anything negative, nor to specifically advise anyone, but only to share our experience.
The throttle does work, but you must lubricate it like any other mechanical item.
The water swivel worked great, but as with all water swivels except those costing many hundreds of dollars more, you must keep it adjusted to get a true cut, and this was true of all portable drill rigs we inspected before purchasing Tim's rig.
Yes there are some parts on this unit made in china, but so are many replacement parts you buy aftermerket for your mercedes or hummer.  We all still continue to shop at Walmart or Sears, and we don't complain about their chinese products.
I'm not sure what electrical system was bad in the other review, but on our rig the engine is gas, and so is the mud pump engine.
The electric winch that came with the rig was moved, along with some other custom requested changes by Tim, and he did not charge us for the modifications.
The bits that come with these types of portable rigs are not designed to commercially drill day in and out, and I never remember Tim implying anything different.  We purchased a specialty carbide roller cone bit that was very large for the our unit, and it handled it great and got the job done.  I would not have expected a $1000.00 bit to have come free with this unit.
All expected manuals  and warranties were with our unit, and much information about drilling came from Tim at no charge, plus we found worlds of information on the internet.

In summary, if you aren't willing to accept that your learning something new when you go to drill your own well, don't by Tim's, or anyone elses portable drill rig, just pay someone to do it.  Also remember that you won't become Bruce Willis in Armegeddon when you buy a portable drill rig.  If you do buy a do it yourself rig, be prepared to learn, which can be tough at times, and know that if you get a rig from Hydra-fab that you will be trading with a most highly innovative and motivated person and company.  A company that may well be an industry leader in portable drill rig production in the months and years to come.  Our thanks to Tims King and Hyda fab for our rig and support.  Support he hasn't charged a dime for.

The following are a few drilling tips form us.

Make sure the rig stays level and secure during drilling operations.  You may want to use additional weight or rebar/wood stakes for securing the rig.
Use common sense in the assembly and operation of any portable drill rig.
Know that the bored well hole will be larger than the diameter of the drill bit.
Buy commercial bits for tough drilling projects.
Use a high quality drillers mud to prevent well cave ins.
Always drill a pilot hole to full depth with a smaller diameter bit before changing to a larger bit to avoid drilling a well that isn't truly straight down.
Work with someone when you can. We went down 77 feet into tough chirt and dirt in less than three hours with Tim's carbide pilot bit, but we were hustling.
