Thanks A Raine, yes I do have the A3 and I have a DishPro 1000 Plus with 3 LNBs.
As Magic static said above, a DishPro 1000 wouldn't work well for FTA and the LNB on it is pretty much useless for FTA.
This dish is a decent one to get for KU band and comes with a decent Ku LNB:
Amazon product ASIN B00507CJZM
There are smaller dishes you can get cheaper, you can get a 76 cm for around $40 -50 and $20-30 shipping, but it's best to get a 90 cm or bigger. The smaller dishes don't perform as well, a 76 cm will work for a lot of channels but it's well worth spending a little more to get the 90 cm.
You could get a dish first and set it up as a fixed dish on one sat just to get used to using it and then buy a motor later on so you can move it across the arc to all of the sats. Setting up a motorized dish isn't all that hard really, but for a first install it's much easier setting up a fixed dish than a motorized one.
If you want C band channels, you'd have to get a big dish, 6' or bigger, 10' - 12' is recommended, biggest is best. Here's a thread of dishes from Craigslist, Ebay, etc that members post up that you might be able to find a C Band dish in if you're interested in C Band, I just got a 12' one from one of the posts on here a week or so ago, there is Ku dishes here and there within this thread too:

When you get a dish, if you need help, just post up either a new thread or within this one and there should be tons of people willing to help.
If you're on a real tight budget, you could mount a FTA LNB like this:
Amazon product ASIN B0087OTUJI
with a bracket like this:
Amazon product ASIN B002NHEZZ4
onto the dish that you have now and receive a few channels off of a few sats but I wouldn't really recommend it because with a small dish it can be very hard to setup, especially if you don't have a decent meter and it's the first dish you've ever setup. If you don't get it spot on it won't be at all reliable. If you do try this and don't get any results, don't let it deter you away from FTA, the small dishes are night and day compared to larger ones performance wise!
