Thanks KTM and others,
Thats what I was thinking, original vs moded It came with globes so.... but then the cost of replaceing globes over time vs LED's initial exspense and not need to replace them.
Quick check of some prices has them at Just over $100 local to do the playfield (different colours for each type). $120 from a online supplier and $170 for an eBay kit. I just need to check with some of our suppliers for work and see if I can get stuff cheaper.

Simon.
