I think this year at megacon I might get a gundam kit... maybe ... all the ones there were stupid pricey :/ but this year i'll have a credit card! (oh god please help me... I'm gonna regret this later)
Look up online prices before you go if you're gonna buy one. Just so you have an idea of what's a good deal and what to avoid. :x
Also make sure you're looking at the right kits; a lot of mechs have had multiple releases over the years, and you don't really wanna end up with an 80's/90's kit of something that's had a newer release. :x
High Grade
1/144 scale kits with these logos on the box (the HG is the important part; the subtitle just specifies which timeline the mech is from) were made in the last 15 years or so and are pretty good quality. Obviously the older the kit, the worse the quality though, so might wanna be a bit careful.

Master Grade
Kits with these logos are 1/100 scale, have more detail/parts than the 1/144 HGs and are obviously more expensive, but have a much more limited selection of mechs. Pretty sure some of these are even older than the oldest HGs at this point, but you generally can't go wrong with any of the 2.0, 3.0 or Ver. Ka kits.

Real Grade
And then kits with this logo are 1/144 scale like the HGs, but have as much detail (or sometimes even more detail) than MGs. They're in the middle ground of the two grades in terms of price, but there are only around 12 kits out so far. The line only started a couple years ago, so any of them are good really.
Clearly it means that girls wear buns to contai their super Saiyan Swagger.
I lost it when I saw that episode of DBZA.
I've lost it at pretty much every episode of DBZA since they first got to Namek. ._.;
Quack!
"Lord Frieza, Vegeta's really giving us a pounding!"
