Alright I need a D15B7,D15B5, D16Z6 or D16Y8 for 300 or less. The B8 doesn't have enought HP for me and I really would prefer not to buy another D15B2. Because for me to get the HP I need I will have to convert it to Multi-Port FI. And unless you have the parts to help me convert it I would rather go for the B7. So any help would be appreciated.
