If you are currently using a Radeon DDR then I'd DEFINITELY suggest getting a 4200 now and then save up for a new CPU, in a few weeks AthlonXP2000+ to XP2200+ should become bargains with the new Barton AthlonXP coming out.
As for which 4200 to choose, well 128MB is definitely better and 64MB will become a pretty major limitation pretty soon. Although 4200-64MB cards are pretty much guaranteed to use 3.6ns RAM and hit 300/600 once the RAM limit is breached a 4200-128MB at the default 250/444 actually equals the perf from the info I've read, and 4200-128MB nearly always use 4.0ns RAM and hit 300/550 making them faster than a 4400! The choice is yours of course, but I'd get a 4200-128MB and wouldn't be too concerned about the DVI-to-CRT converter as for most it's only something to play around with anyway!
