Do yourself a favor. Bite the bullet and get an Escalara. I did not want to put out the money either but look at it this way:
1. How much money will you lose not being at work from an injury moving a game?
2. How much money will you spend in medical bills after being injured moving a game?
3. Do you really want to spend the rest of your life living with the pain from a shoulder or back injury that can't be permanently fixed?
4. How many times can you keep bothering friends to help you move games and how bad will you feel if they get hurt helping you?
And finally, the resale on these things is pretty good if you maintain it. Some go cheap on Ebay because they look beat and the owners who used them in industrial applications do not realize how many pinball guys would like to have one. Even if you pay a high price for a new one it will only lose $500 of value ten years later. Meanwhile you saved your body, did'nt damage your games, helped your kid move his fridge and washing machine and just plain made your life much easier. Sure your neighbor's and friends will use it a bit, but it is still worth it to even avoid one back injury that we are all so prone to getting moving these games. Especially with a WOZ!
If you use it 20 times in 10 years with $500 in depreciation it costed you $25 each time you used it. And those are some pretty conservative numbers when you throw friends and family into it.
I'm glad I spent the money for one. Most people probably are and wish they had done it sooner instead of later.
