I just want to chime in and say that I tend to agree with collinglover. A good solid CDR device is the way to go. Rack Mountable tascams are worth the investment. to save some money you might try going on eBay or somewhere like that to get one that is used (from a trusted seller!).
Additionally, although I have never done it, you can probably go with some consumer grade CD burner equipment for a little cheaper from a place like best buy.
Finally, I like the iTunes/Audacity route. We simply grab the cd master after service, stick it in the mack. Convert to MP3 using iTunes, if it sounds great immediately upload it tou our podcast host (Hipcast) and the whole service is online in about 15 minutes for about $5 per month.
