BagBoy Navigator 2 Electric Cart

I have owned the navigator 2 for about 2 1/2 yrs now. I'd never buy another. Within the last 8 months I had to replace the front wheel because the bearing went bad (no u can't just replace the bearings). Cost - $75. Then the remote control went. Cost to replace - $170!!!!!!!!! ( for a remote? c'mon) Now it won't power up. I've checked it out extensively and I THINK it's the control unit underneath that went bad. I can't even imagine what that would cost. I'm done sinking bucks into this money pit and I'll never buy a bag boy again.
