Need advice on a decent Sun server for learning purposes

I’d like to purchase a Sun server from ebay so that I can set it up at home and become more familiar with the Solaris 8 OS and installing web servers such as Weblogic and Websphere (for learning/development purposes only). I’d also like to install Oracle 8i.

I noticed that there are many Sun Server models out there and they can be quite expensive. Obviously, I don’t need a super fast machine, just something that can handle the apps I just mentioned and be able to have a decent response time. Can anyone recommend to me some reasonably priced “starter” Sun Server models that could handle the job?

Thanks.

I’ve been thinking of buying one myself to get familiar with Solaris and when I asked advice from others, I was told that an Ultra 5 or 10 can be picked up cheaply and would do the job. I don’t know about running Oracle on it, as I’ve heard Oracle is pretty demanding, but maybe check with them about min spec?
