I fiddled around with the search forums section and found some useful advice on upgrading a G4 Sawtooth, but I want to take it one step further; Which company should I buy from. I was first going with Sonnet but read that some people condemn it. And then thought about Powerlogix and once again reading in the forums was shot down. So I'll give a list of upgrades that I am interested in and you can give me some input. Giga Deigns Never heard of them till I saw them on eBay. SonnetTech I've known this company for quite a while I was going to post OWC but they don't have a fast enough speed (>1.6 Ghz) Powerlogix Kinda sketchy on these people after reading some of the threads If I missed a company tell me and I'll post it. Also I know there are other options like buying a faster Mac but I love the Sawtooth's expandibility and I am not going to buy Intel anytime soon. I love PowerPC, mostly for my old school gaming and hopefully some new school when I complete all of my upgrades.
