How thick is your wallet? How much do you desire a shiny kettle? The beer will taste the same IMHO FWIW.

Check out the thread Revvy's linked to as well.
Once you've conditioned an aluminum kettle, it's 100% safe for brewing. Just read up on doing so (basically, boil as much water in it as you can) and remember to leave the layer on the inside.
I've used an aluminum kettle (I made it from a 32 qt stock pot) before. My brew-buddy uses it now. I've migrated to keggles for the mash tun and boil though. I also have a 10 gallon kettle I made for an HLT as well as the 10 gallon BoilerMaker I purchased some time ago. Moving forward, while the size is still good, I'll be making/using keggles. I have a few 'spare' kegs I can convert, as well as a fairly local source for more of them.

I've been doing split batches for years and it's time do brew in one pot. I appreciate the help from everyone~! I can arm myself with an alum kettle and attach a ball valve and site glass for less money than a plain SS kettle! Why wouldn't I.............

Aluminum is fine, but don't drill holes in it for ball valves made of steel/bronze... that'll eff sh!t up

Just be sure to get the correct size aluminum pot to convert into the kettle. I'd also use a stainless (3-piece) ball valve and get a dip tube to work with it. You can go with the 1/2" NPT to 1/2" compression fitting, a few washers, silicone washers/o-rings, and dip tube all from Bargain Fittings. Should be about $45 plus shipping. The dip tube will help you to extract more wort without having to tip the kettle to extract. Also, use 1/2" ball valves, not 3/8" for this. If you want to go larger, you can, but make sure you can get everything in the larger size (1/2" NPT is far more common).
BTW, I've designed, and make, my own sight tubes/glasses. All stainless fittings and borosilicate glass tubes for it. No worries about temperatures this way (unlike with the polycarbonate tubes).
