I went through that with a machine I bought in 1997, $2500 machine on sale for $1800. I could pay $400 for a new mother board, but they would not give any warranty and if it didn't last when I took the machine home I would be out the money. Even though the repair was less than a new machine I opted to buy a new one. I got a new machine on sale for $1100 that had a larger throat and (most important) a new warranty. It was definitely worth it.
