Puttputt's ebay torch talk inspired me to bid, and win, a brand new Harris oxygen regulator for a great price!

Ebay seems to be a great place to find this kind of stuff – I was able to buy a high quality heavy-duty regulator for less money than the value priced economy ones usually sell for at the local welding supply houses. So now I’m going to have to chase down a matching acetylene regulator…I’m a sucker for a deal
