DW,
If you feel the need for a PS2, that's your call by all means, but just be clear about the 360 and Wii before your right them off. By the sounds of things you like things to look purdy, the PS2 is going to date in a matter of months, when you're looking at PS3 / Xbox / PC reviews.
If you're looking in that price range, you can look at the 360 Core for R2599 at Hi-Fi Corp. It's similarly kitted out, but has room to expand and will last you 5 years as oppossed to 1. There are already a number of budget titles available in the R200 range.
There are Plenty of XBox 360 exclusive titles coming out, they're not just PC ports, on top of that, Microsoft has gone out of their way to try make sure they've got more Japanese content coming out on the 360 than the PS3! (Dig up some TGS coverage)
If online play is your thing, then XBox live! online services kills anything the PS2 has to offer.
Having said that, don't write off the Wii, Nintendo is represented in South Africa and the Wii is supposed to land here before the end of the year. If you want resellers, go to
