Sheesh! Any PDA that keeps working is a "good and reliable PDA to use"! LOL!
I've said this before, but I'll repeat it due to the question. Any Palm OS PDA will run Cachemate. A higher end model with lots of memory only allows you to store more cache data.
I'm not familiar with the Palm model mentioned, but we use a Palm Tungsten E2 and love it. (They're going for about $100 right now on eBay)
