Developers can get one for $3000. See:

A basic PC with a Celeron chip definitely seems to be best performance/$
400 MHz Celeron 140 k / $600 = 233 iters/sec/$
Most other PCs seem to cluster together:
2x600 MHz Pentium III 2x200 k / $2500 = 160
800 MHz Athlon 280 k / $2000 = 162
400 MHz Pentium II 132 k / $800 = 165
350 MHz AMD K6-2 84 k / $550 = 150
The Alpha mentioned above does almost as well, although from an
assembler it's not as good:
600 MHz Alpha 21264 400 k / $3000 = 133
600 MHz Alpha 21264 400 k / $3850 = 104
Sparcs are a bit behind:
440 MHz UltraSPARC-IIi 190 k / $4000 = 48
366 MHz UltraSPARC-IIi 155 k / $3500 = 44
And the less said about HP PAs, the better.

An iMac with PowerPC G3 chip is not great value for money as far as
ECDL is concerned, but on the G4 Dan Oetting's Altivec code now does
about 286 k at 400 MHz which makes it do rather well:
350 MHz PowerPC G3 70 k / $1000 = 70
400 MHz PowerPC G4 286 k / $1600 = 179
All these ratios should be taken with a pinch of salt since speed
varies a bit and prices vary a lot. I picked some representative
prices from web sites at www.dcginc.com, www.thelinuxstore.com,
www.swt.com, www.apple.com...
