The obvious one that fits your bill is the Toto Drake II. It is a good value given all its bells and whistles: Universal Height (comfort height), Sanagloss stain resistant finish, Double Cyclone Flush, and qualifies for a "Watersense" rebate in jurisdictions that offer them given that it is 1.28 gpf.
It's a 12" rough-in toilet, it has a 3" flush valve (TOTO being an originator of this), it's a two-piece, installation is straightforward, and they give you the hardware to do a double-nut mounting of the tank to the bowl (one nut to secure the washers and bolt head to the bowl, then another nut to secure that assembly to the base, which makes for a more secure install then just one nut holding the bolt through the tank and base). It uses a standard flush valve, easily-replaceable with the Korky Large 3" Flush Valve kit (made in USA) and the fill valve can be replaced with any modern fill valve that has an adjustable refill ratio. Toto has an excellent parts store as well. However, on the fill valve Terry recommends that you just go to Lowe's and pick up a Korky 528MaxPerformance (528MP) fill valve, which is basically-identical to the fill valve that Toto would sell you as a replacement part (Toto TSU99A.X). Both of those are made by Korky in the US (Wisconsin).
The key with Toto is QUALITY. It's well-made no matter where it's made. Many of the Drake IIs are made in Georgia USA.
The Toto Drake II is going to be CST454CEFG. There's also a 1-gallon-per-flush version that they make that is becoming very popular and looks a little different on the tank (CST454CUFG). U instead of E in the model number. Basically-same-price.
Another option is an original Drake. A real workhorse toilet for a little less money. It comes in Universal Height (CST744EL) about $100-ish cheaper than the Drake II. It doesn't come in Sanagloss at Universal Height and doesn't have the Double-Cyclone Flush, which uses a swirling action, without little holes in the rim, to give you a better bowl wash. It has the same other benefits as the Drake II: quality, easy install, easy part availability, 3" flush valve, etc. It also comes in a 1.6gpf, rather than 1.28gpf, version (CST744SL) if you don't want the more-water-saving flush. Both flushes dispatch waste very well.
If you go with Toto and look locally, shop around. Call a number of plumbing supply places in the yellow pages and ask for a quote on the exact model and color you want. Prices vary wildly at these places and with plumbers. If you call 4 or 5 places, you should be able to get a price close enough to the online vendors (30 percent or more off list). Use Terry's prices in the red box link above as a guide, although that link doesn't have all the models he or Toto sells.
