Mmmmm. ....
The reality is this ...500 to old, too small and really too limiting.
The Bell is the way to go ...if you could get a 407 probably perfect for what you need to cater for all eventualities????
But of course ...expensive ...
Remember ......
"You cannot make strawberry jam out of goat droppings" .... does'nt matter how hard you try... it will just not taste right!
Identify your major money earner ... and cater for that market the best way you can.
Good luck
