Project Align it CartridgeAlignment Gauge is good?

Agree with the other posters. Most other alignment gauges I've used/seen are toys compared to the Mint.

Serious rigs deserve serious tools, and Yip's quality, service and responsiveness are second-to-none. Further, the instructions he includes with each Mint are the clearest I've seen.

and geodisc of mfsl is good?

with the investment you've made in your equipment, agree with posters above that a Mint is the way to go. For all of them, the "method" is simple, but the effort required to get it right can take considerable patience.

Just get a 309 alignment template and be done with it...

It's $20 here:

It's what I use and it's simple, accurate, and accounts for the variable pivot-to-spindle distance sliding base.

Orionpcgames,

I'd recommend you do a search of this site regarding protractors. The pros and cons of each design has already been thoroughly debated (many times).
