Congrats on the new blower!
While these blowers aren't cheap they also aren't really expensive. I'm surprised you didn't retire the 7000 a few years ago and keep it as a backup. I bought a BR600 back in '05 and it is now the backup to my BR600 Magnum that I got last year. I pulled the old blower out of the shed a couple of weeks ago and made sure it still runs. I replaced the fuel lines and primer bulb. It starts on the first pull now. It needs a new trigger and shoulder straps but other than that, it's fine.
