rec-ball: gotta be a tippmann for thier rugged reliability
tournY new marker: have a look at the new pirahna evo, £250 for a marker with eye. Good price and pretty reliable.
Tourny 2nd hand: check the classifieds, anything from Angel IR3's, autocockers, intimidators. best bet is get to a walk -on and try some out.
See what you feel confortable with.
Crossover marker: Personally i would have a VF Tactical. suits both styles pretty well.
hope this helps.
Someone else will be along in a minute to give some other advice also.
Listen to all angle's from everyone and you will see how much of a personal preference it really is.
