Some time back tried PS PRo 3 and received little support. Have not tried PS x5 for this reason. Just tried Corel After Shot Pro and was unable to get support? Just bad luck or me? Any help would be appreciated as free days are running out/of just go to Light room 4 (???)

I have a Yongnuo YN565EX. Might check it out on Amazon, very powerful and compares favorably with the Canon 585 or whatever their top priced one is. Have a Canon 50D and soon will move to a 7D. Very powerful, in fact it must be toned down somewhat! They also have a web site which is helpful. Recommend it. Price is around $175, have tried and used a Promaster 7500EDF and DOES NOT have the 'power' nor cotrol options the Yongnuo has.
