Ok reliability wise, ones an electro the other is a mechanical. for my money I'd go for an LED, although for not a lot more cash there's a lot of LCD's/IR3's going!
the main problem is i dont actually have to much cash at the moment so my new marker would basically be paid by the sale of my old automag68 with inteliframe and lvl10
However if you get a dodgy one like i did then you may aswell put it in the bin and cry about your wasted money.
Mine was sent back to wdp. They told me the whole body was twisted and it would cost more than the gun was worth to fix it. Luckily my team has some very good friends at WDP and they sorted me out.
I reckon you should either stay with the mag or get an LCD its a better gun, looks better, more features (timer, sight rail mounted intelifeed etc) and a lot better quality control.
You can get some cobra stuff for LEDs, but more for LCDs and IR3s
Mate, for the price you are looking at, with that led you can't really go wrong. The led is the angel before the lcd, different valve, and a different display.
Good intro into angels, well worth it, but make sure it's working well.
