having been entrenched in PC world for a bit, FTP programs were the one thing that I having a hard time with in the Mac world. I mean, I remembered about Fetch from way back when, but Fetch never made much sense to me.
when I first re-entered Mac-land from PC-land, I used Bulletproof FTP -- it has a PC version as well, which works fine, I suppose. WS-FTP had no ported Mac version and there was no way I was using CuteFTP.
after trying out many (many!) FTP programs, I think you're not going to do much better than Transmit. it's solid. and sure, it's $30 but my dad always said, you pay for what you get.
just my $.02.
