Personally, I think the Weber quality is OK. Recently they have been sending kits with the most commonly replaced parts upgraded - the jacks and switches. Even the stock kit will get you a good sounding amp. I have a Weber kit that I used almost all stock parts and I'm extremely pleased with it. Mine didnt yet have upgraded jacks and switches, so I did use Switchcraft and Carling. I would suggest getting better tubes. The Chinese 12AX7s seem alright to start, but I have some other ones I put in. The Chinese 6L6s it came with sounded surprisingly good, but Weber doesnt match tubes and they are way apart in current draw.
