If you're mainly camping in warm temperatures, go for a tent where the inner is 100% mesh, except for the floor.
I just picked up one of these http://www.amazon.com/Ledge-Sports-S.../dp/B007U54YLE from Livewell Sports (US) and shipped to SG total cost will be < $200.
Its rare to find an aluminium pole free standing dome tent with 100% mesh at that price.
Also, www.GoLite.com is having a tent sale - you could get a very light but very waterproof one for a good price. The 3 person teepee style would be luxurious!
Only sharp knives are interesting.
