Before this thread gets kicked over to the 'newcomers' board (where you'll get more responses), I just have one recommendation for an easy cologne, great in hot weather, and you can find it for under $50... plus if you like Allure Sport you'll probably like it.
Imperiale by Guerlain (google it and you'll find an inexpensive retailer).
Of course if you stick around on these boards you'll learn a lot more than you ever thought you'd know about fragrances.
