I don't really want to get into the whole '70's are better than modern!' hiwatt thing. But Lew if your stil after one....come try it! I'll do you a deal son ;)
I love the hi-watt tone, but as Heavier said they do need to be played LOUD to enjoy them properly & with fanes they are nice, but with V30's the sound pretty good as well (more bass added!). I wouldn't swap personally
