Sheesh! Well, I couldn't do it!
Ever get that 'gag reflex' going? There I sat, with my finger quivering on the mouse button, ready to buy the Zalman twins, but I chickened out! I guess I hate flower fans more than I thought.
Whew! That was a close one! Instead, I ended up ordering a Tuniq Tower T-120 cooler. It was $57.84 ($48.98 + $8.99 shipping), so that meets the OP's "~$50" criteria. Man, those things hard to find *in stock*!
Anyway, I'll let you know how it works, next week, assuming it doesn't get back-ordered on me...
