I stayed at Buddy's twice last year and was consistently impressed with the dive op and the resort itself. Capt Don's has the reputation, but I thought the resort was looking a little tatty and in need of some TLC. However, the pizzas at Capt Don's are awesome, so I used to wander round from Buddy's on a night for a fix! They are right next door to one another, so it is literally five minutes.
If you are going to be doing a lot of shore diving from a truck, then Buddy's drive-thru fill station is great you pull in, dump your empty tanks and pick up full ones, then you are ready to go. Easy!
Dive-wise, make sure you do Karpata (there are at least four ancient anchors on the sheer wall to find, one at 10-12m and the others way down around 55-60m) and definitely do a night dive on the Hilma Hooker wreck!
