Dimarzio's or something else?

Loads of great pickups out there.
Dimarzio are fine but personally I'd get something from one of the 'boutique' makers, Bareknuckle, Fralin, Lollar, etc. You can usually contact them by phone or email and get advice as to which model is best for you (something lacking from larger companies).
The extra cost isn't wasted IMO, you might outgrow your cheap guitar but you can always put the pickup in your next axe.

love the mojotone custom classics in my ES345. superb! however, with pickups, what may sound great in one instrument might be a dog in another

dimarzios are a solid choice. They have an exchange policy too, so if you put a paf in & find you want a little more beef or a little more chime you can switch it out for a different model.

I would start there (seymour duncan are also great) before getting into super boutique. I think you have to really know what you want before going that route.
