What are your goals, psycho? There are a ton of options for you in thi category:
NP massPump stack - for the money, unbeatable. Creatine, citrulline, arginine EE. Massive pumps, $20
Storm/Shock Therapy - $55 total, effective, nuff said
Clout/Body Octane - it doesn't get better than this. It's very expensive, but it is awesome for strength, endurance, and recovery. It's hard to overtrain on this stuff.
Xpand - cheap and very effective. Whopping doses of arginine and creatine in one product.
Vassive Stack - Never tried it, but killer ingredients.
Horsepower - sickest pumps from this kind of product, great ingredients, lots of creatine, cheap.
And if you just want pumps, you're best off taking an NO pill twice a day, and creatine separately. Here's some good NO stuff:
SAN Vaso Flow - brand new, but kick ass ingredients. You'll have to visit the dark side to buy it.
NOX3 - cheap AAKG
Nitrocharge - cheap and effective, di-arginine
SAN Ox -

keep in mind that arginine pumps aren't really effective at building mass, and don't enhance performance. I'd call it a cosmetic supplement, even. Citrulline, on the other hand, enhances performance and recovery, AND give great pumps. If you've never tried 6gr citrulline a day, you definately should. You can use OX or cheaper bulk.
