The Megatron is a great pickup. If you're not getting on with them, maybe get them closer to the strings.
I've seen a set of two go for $150.
What are you going to put in their place? I'd go Magnatron (neck), Powertron (Bridge) and TV Classic (middle).
The love of money is the root of all evil.....damn, I could use some really rather naughty right now.....
