Hey all. I've decided it's time to bite the bullet and start toying in the digital realm. There are two projects I'd like to put together in the future:

and
http://www.diystompboxes.com/smfforum/index.php?topic=80878.0
These projects use the PIC16F684 and PIC16F84A respectively. Can anybody recommend a relatively inexpensive board to program these (and hopefully other) PICs? Id like to be able to expand to other chips as I learn more about the pros/cons of each. I'd also need connectivity via USB (I say this because a couple of the DIY routes I've seen use a Series port which I don't have). I saw one at Futurlec but wanted some suggestions from you guys. Thanks!
(sorry if this has been covered a million times, I wasn't able to find anything)
ughhhh wrong forum, sorry, supposed to be in digital...
Most of the USB ones are relatively expensive... I went the cheapy route and bought a serial port programmer for ten bucks or so. My computer didn't have a serial port either, so I hacked one together. All you need is a PCI card slot with a suitable hole for a serial connector, and a DB9 port to stick in it. Then you just attach the DB-9 connector to one of the serial ports on your motherboard with a cable. Nothing to it! Didn't cost me a dime. All works perfectly.
Pic16f84a is icsp ie you don't need to buy a complex programmer for it. You can make one your self with just resistors and diodes.
Here you. Some details.

Programmer schematic and layout on vero board. Just few common component and you got your programmer.

Mentioned above correctly usb one are very expensive and very complex to make. But if you dont have serial port in your pc/laptop you better buy a pci/pcmcia/usb serial port interface.
