I didn't mention this before, because it looked like the OP was only
interested in cheap programmers.  But I might as well point out that I
use Microchip's Promate II to program the 18F series, and have had no
problems.
Regarding speed, I was impressed with how much faster the 18F's program
compared to the 16F's, which I assume is due to changes in the flash.
With the promate, I can program an 18F452 in about 17 seconds, which
includes verify at 3 voltage levels.  Just the programming takes about
12 seconds.
