No one here will try to sell you anything. It seems that the majority of professionals and non-professionals here prefer Toto toilets for their performance.
Prices for the well rated one-piece Toto Ultramax, for instance, run between $375 for a standard height round model, and about $100 more for one with an elongated bowl at the ADA height (16" to the bowl rim), which is more comfortable for many people. You'll see that those prices include shipping, in case your local plumbing supply house doesn't carry the brand and model you want. Generally, two-piece toilets (those with a separate tank) tend to cost less.
Another well liked toilet here is the Kohler Cimmaron, and you'll find a review thread on that toilet if you look.
I think spending more to get a really good toilet is money well spent. It's up to you.
