xtra is good but I think the custom 98 is more reliable the xtra is very good and if you want a spyder i would wait a while and get a shutter thats about $60 more than your limit.
Anouther idea is one of those new cheap electro's the black draoon or somthing like that. It sells for about $200 bucks. It's to new to know about reliability but the trigger is suposed to be hi quality (fast). You should be able to find the review on this web site and pbreview.com
but as a newbie u might want to keep to a low price semi-auto for now not saying that there bad but i think the semi-auto is easier to maintain of course im probably just saying that though since i like spyders more than the black dragun
