Festool CT 33, Alto Attix 30, or Alto Attix 3?

[m8]

I have narrowed my search for a new dust extractor down to three models.  I am attempting to make my final decesion and wanted to see everyone's opinions on which one is the best.  I am looking at the following three dust extractors:

- Festool CT 33
- Alto Attix 30
- Alto Attix 3

I will be primarily using the dust extractor for fiberglass related projects and a few woodworking projects.  The projects will involve mostly sanding but also cutting, routing, and general shop clean up.  As always I greatly appreciate everyone's opinions.  I have already read many forms on the particular Festool Dust Extractors but have been unable to produce decent search results on the Alto Dust Extractors.

I have both a CT-22 and an Alto Attix 3.  Unless you want to lock Systainers to your vacuum, I would go with the Attix.  It is a bit quieter, the filter cleaning feature works a little better, it is easier to use in wet mode, the run after tool trigger release is a little bit longer and it comes with a very nice set of cleaning tools in the base price.  It has all the desirable features for sanding work, including a rheostat to control the suction, filter cleaning and several options for filtration.
