The
Meade Redtail might be the best way to go for your budget, it seems very
tough, with a rubber armor coat, its full water and fog proofing, comes with both hard and soft cases. And its 25-year warranty allows you to return it if it gets broken (even if its your fault) and they will give you a full refund - no questions asked or trade in for a better model. After some digging around for a suitable tripod I came up with the
Slik pro 330 DX tripod the reviews say its very well made and sturdy (i.e. not wobbly on it's legs, it's a
light-weight tripod so you'll still have issues with things like wind
and vibration, but you'll get that from any light-weight metal tripod), and seems like the perfect tripod for your budget. Scope and tripod together would ring up as $252.00.
