New Legand 12oz CO2 bottle

[Roboteernat]

When I get the bottles I will make a call to some companies to find out.

Regulators...
There are many out there, and I'm thinking the aquarium regs would be best, http://r.ebay.com/MUDslH is an option, but what do you guys use? Trevor regs are difficult to find and my larger gas reg is just way too big for these applications.

I have searched through these forums for regulator comments, but could anyone suggest one now with Amazon eBay links?

Edit, is this suitable? http://r.ebay.com/Xo9Vqe

Thanks
