Thanks everyone for the input I was bidding on an eBay auction on a couple tonight missed an 18 that went for $120ish I know I should of bid more was at work and missed the end of the auction

but I got a 6.7 for a fantastic price so couldn't resist.
And I agree Fraser I was thinking 4 e/p would be the perfect number to have i was thinking maybe the 18 next? Getting ahead of myself need to look through the 6.7 first
