i had the 44.2 and durango v3. went to xb4 and havent looked back to be honest. spares now not a prob as most shops have them and they are gaining a following in most areas. initial issues have been ironed out so buy with confidence. xray quality is amongst the best out the IMHO. any questions feel free to call the shop. will even pass on my full setup for b44.2, dango or xb4 depending on which route you go
