Let me put my 2 cents in about price. If you wait a bit, Softmaker has VERY good sales. I got Textmaker for like $20 during a sale. They usually have such sales several times a year.
My only problem is that now I use pdaXrom, and it has gnumeric and abiword. I bought Textmaker, and loved it, but abiword does the job well too.
If either could run on pdaXrom, then I'd probably still use Textmaker, and buy Planmaker though.
