You may choose a serial port programmer like a JDM programmer or usb based programmer like the gtp usb lite, Plus, June bug or the Pickit 2lite. All will work fine for a 18F4550. Every programmer is discussed here in eda before. Just have a search.

you must use a gtp usb LITE and the gtp software v3.55
if any of the two is not right, nothing can work.

with the pickit2 you can program AND debug (trace) your programs. the gtp is only for programming.
also the gtp usb lite works only with winpic v3.55 - so there are quite no updates for new pics since a long time.
so for me pickit2 wins.

I helped someone for this type of programmer before, search on edaboard and see if you can still find it.
By the way, for all the resource you can build a gtp type of programmer, you can almost do the same thing with PICKit 2. Why not give it a try when you get some time.

Do you have gtp-usb PLUS?
If your gtp usb goes LITE then you need the usb host.

Yes, winpic800 is a freeware. But if you want to use the full potential of the software, you need the programmer gtp usb+ from sisco.
