What do you use yours for? How's performance? What Solaris version are you running? That's cheap enough that I'm considering buying it just because.
I'm currently using mine as a Sun Ray server (Sun Rays are thin clients sold by Sun which are solid-state devices that have no moving parts -- not even a fan) and an Oracle development server (most of the work I do on the side involves DBA and PL/SQL development). It also serves as my build system for OpenSolaris ON sources (the consolidation of OpenSolaris that contains the kernel, drivers, and the bulk of the userland), as I'm currently improving support for my Tadpole SPARCbook 6500, which requires that I have a build environment that's capable of building ON in a realistic amount of time.
In terms of performance, a single UltraSPARC-II processor will be blown away by any modern x86 processor; however, given a sufficiently multi-threaded workload, my E4500 would compare to any modern x86 processor. I can do an MPlayer build in roughly 2 minutes, as this is important, given I'm also an MPlayer developer (you'll see my name in the AUTHORS and MAINTAINERS files in the MPlayer source tree, because I maintain the MPlayer Solaris and AIX ports). A modern x86 system compiles MPlayer in anywhere from 3-5 minutes.
I'm currently running Solaris Nevada 64a (this is an Alpha release of Solaris 11).
I would hold off on purchasing an E4500 and A5200, unless you're in an area where power is sufficiently cheap. Given I live in Tennessee, which has some of the cheapest power in the entire country, the E4500 and A5200 only add $50 to my power bill/month. You'll also need to worry about cooling, which is very important, especially if you live in a hot and humid region.
If you're still interested in purchasing a SPARC system, I would recommend an Ultra 80 or Blade 1000. These systems can both be purchased for $200-$500 off eBay in loaded configurations. For example, an Ultra 80 /w 4x450MHz UltraSPARC-II procs (4MB cache /proc), 4GB of memory, and at least 2x36.6GB disks or 2x73GB disks should be in this price range.
