@frosty - I love the SEED Mobile GINNs & GuAIZs. Excellent designs. That's what I'd do first. If you want something with more traditional Gundam stylings though, the Striker Dagger would be the way to go. Either way, I'm thinking you'll find the kits pretty simple given the content of your signature file! I love the roden fokker. I'm new to Gundam kits myself-- while I've always been a fan of big stompy robot cartoons and sci-fi in general, I've primarily worked with WW2 armour and a lot of scale historical figures.
@jay12472 - I think the 1/144 scale stuff is a great place to start. The very simple kit I'm doing (link below) is a 1/144 non-grade kit. You can also get 1/144 High Grade kits that are about twice the cost and twice the number of pieces/complexity. I'm starting with the 1/144 non-grade but am already looking forward to the HG. As you can see from Aurora-7's daughter, kids can even manage complex 1/100 scale kits as long as there's sufficient guidance and motivation. If you can't find any in the local model shops, I'd recommend http://www.gundamstoreandmore.com as a cheap place to get a couple 1/144 kits. You may want to snag one for yourself and join us!
Speaking of people joining
mustangs102 will be joining with a kit-bashed/custom creation of a MSZ-0018 Triple Zeta Sentinel - I'm not sure if it's made from a combination of kits, scratchbuilt parts or what (nor do I yet know the scale), mustangs102 will have to fill us in. Either way, welcome! It's cool to see such an ambitious project!
As for my own kit, I have 3 more seam lines to sand smooth and I'll be on to puttying. Things are going at a good pace considering the simplicity of the kit. I wasted a session on modifiying the ankles to get more mobility but it ended up being not worth the trouble on such a simple kit.
