I don't think you over paid for what you got at all - the machine with all the extras would be $300+ easily in most parts of the country - the table, I have only ever seen them on this board, so as a bit of a rarity commands a good dollar. It's a lovely set up and you are all set to go - enjoy it!
You only get to go around once in life so you better make the most of it while you can, if it makes you happy and doesn't hurt anyone then go for it!
