I finally broke down and packed my E2 black rainbow up and sent it in for a cleaning. I was a little hesitant to ship it so I sent my se first and got it back with no shipping damage. Just got it back today and its so clean I kind of hate to use it. The cleaning was $75, HEPA filter was $36 and bearing adaptor asm was $7. Shipping one way was $20. I would have spent more than that for gas to take in down. Should be good for another 7 years or so.
