Themes for XP, a Good Idea?

DOes the enlightened IT forum think its a good idea for me to load some XP themes?

What sites do you guys recommend if so?

It takes up a chunck of memory, so if your computer is old, I wouldn't recommend. Otherwise, it's a personal call. I haven't had any problems with them. I use IconPackager, StypeXP and CursorXP.

I have a Athlon XP 2700, 1 gig of 400mhz DDR ram, and 240 gigs of HD space (80 gigs is MMA hehe)..

ThemeXP seems to be working really well on my comp. What's the difference between using ThemeXp and the regular Desktop Properties?
