buy 2nd hand, you can get some epic bargains, try to find some local trials riders, they'll help you learn and progress faster, and most of the lads on here know trials bikes like the back of thier hand they will be able to check out any 2nd hand bikes. if your keen on buying new i'd advise you stretch your budget to the onza pro it'd be well worth it, as it has a much better freewheel (unless the bird has a tensile one?) and dual disk brakes which are (in my opinion) far better than rim brakes.
