For cutting vinyl, I highly suggest a Graphtec Ce5000-60. Many people have had bad luck with SignWarehouse, just to let you know.
If you're going to buy a Graphtec, buy a Graphtec, not a rebranded machine. The Ce5000-60 has the registration mark sensor in case you ever decide you'd like to contour cut. It's a little tedious to contour cut on a Graphtec, but it will do it.
I'd suggest you buy a Graphtec at
Specialty Graphics Supply where you can also get a 5% T-Shirt Forums discount (look on your left here on the forums for "View Offers". You will also get free shipping and 10% off of all supplies (vinyl, etc) for 30 days after you purchase your machine.
As for printing on vinyl, there's something called ColorJet III that I'm about to order a sample pack of, and I'll report back to the forums once I try it out (I just need to check out...it's in my cart right now). This vinyl can be used on any inkjet printer, tho it's suggested you have a printer that uses pigment inks for a longer lasting print.
Otherwise in order to print on vinyl you need a multi-thousand dollar solvent printer, and if you want to print and cut on the same machine, you need a $10,000 minimum machine like a Roland Versacamm.
If you have any questions I'd be happy to try to answer them for you.
