Hi there, and welcome to the forum!
Well, straight to buisness:
I suggest building an antweight for your first robot rather than buying one, for these reasons:
1. You learn more by building one
2. The satisfaction of knowing that 'I built that' is great!

Building an antweight yourself can cost quite a bit, as I've found, my latest one has cost over £150, but thats with full Metal Gearmotor drive and hefty servo flipper, so I doubt a first robot will cost over £100. If you're new, heres a basic guide:

But if you really don't want to build one, try one of the Battle Antz from Roaming Robots. My first robot was one, and although they have a weight advantage of 100g, they're allowed in the RR Ant Arena (NOT at Antweight World Series), but they do have quite weak armour in my experience.
