I have to get some attys for my 3.7/6v journeyman that is going to arrive tomorrow but I have none! I have some LR 510's on the way from heaven gifts but they are a ways away it seems PLUS I cannot figure what resistance I need for additional atty (What do I need? 2.5, 3.5, or 4.5) and is there any place that sells all of them? I see nhaler has the high voltage ones but a lot of sites I cannot tell what they are supplying as they don't list any specs -- are the standards the 3.5? Who sells the 2.5 and do I need it? I know a heck of a lot sell the standard and Pete54 gave me electro-nic-stix (5/$40) and that seems like a good price....they also have a chrome dripper that looks cool, cheaper that Super-T's -- god, that's an entire another discussion!
