This is a regular conversation around here. But, you just got here so...
I'm a bargain hunter too, here's a few I like:
Perdomo Overrun Rosado's - just snagged a bundle of robustos cheap and they is tasty.
Perdomo Reserve Oscuro - great tasting maduro that won't hurt your wallet.
Cu-Avana Intenso - lotsa flavor for low dough.
Cu-Avana Maduro - cheap, mild maduro with great flavor.
Gran Habano Habano #3 and Vintage '02 - way better than the price suggests.
Leon Jimenez Serie 300 - excellent stick that used to be high priced but are being closed out elsewhere for $3/ ea.
Flor de Oliva - nice Nicaraguan flavor for cheap.
Don Lino Africa Kuro - quick firecracker of a smoke that can sometimes be found for around $2/ea.
There's a lot more out there and I'm sure others will pipe up....so to speak.
