Well, you can forget 24p, anyway. Since you're in Slovakia you're choice is limited to DVX100E, DVX100AE and DVX100BE (are they even available? have yet too see one here), all of which are 25p/50i.
I'd say spring for the B, if you can. It's all about $, really. 100B > 100A > 100, if you don't care about the price.
