I own several APV's that cost around $200. Each of them is extremely well made and work exactly as they should. I expect all of them to still be working 10 years from now as well as they work today without me spending any additional pennies for repairs. They all have lifetime warranties which means they could continue to work far longer then 10 years BUT that could require the vendors to still be available to make repairs so I guess only time will tell how that works out.

I enjoy my Ego Twist and my Hogmods, Buzz Pro, Evic, 5 VT box mods, ect. but none of them are going to still be working without repairs that will cost me more money IF they can be repaired 5 years from now not to mention 10 years
I've seem $500 APV's I'd love to own, BUT that's just more then I can justify for one APV even IF they would work for a VERY long time

I enjoy variety so putting all my funds into ONE APV doesn't work for me.
