I love my EB22 Runs at just under 6ftlb. yes it's loud, but you can get an adaptor for a silencer (altho' it's pig ugly.).
It's not welded by the way, it's soldered, and yes you can split it to work on it. Someone on here has done this I believe, getting it polished or refinished.
For mods etc.. I have to admit the 2240 would be a better bet, there's far more out there to cater for changes, from the UK or States (crooked barn are very popular for bits).
