Rent vs. Buy?

[Vtach]

Buy your own reg setup and BC system.  I would recommend buying new but if you are going to buy used, make sure to have whatever you buy gone through by a tech before using.  Don't cheap out on regs.  You don't have to get the most expensive but get something well known with a good reputation and supported by your LDS.  There are many good brands out there.  You can find deals new or used online if you know what you are looking for but you will get good service and advice if you stick with your LDS.  It is a tradeoff that there is really no easy answer for.  Personally, I like to stick with the LDS for the important stuff.

Try some searches on .  You will definitely get a wealth of info there.

Good luck on the justification, hopefully she will be understanding about spending good money on good equipment and good training.  It is worth every penny when it comes to safety.
