Do check out the posts in the thread listed by Kokopuffs.
Also, keep in mind that there is no single company known as "Sabatier". The brand name of "Sabatier" actually covers a number of different lines of knives made by a number of different companies, almost all of which were traditionally based in Thiers, France (south of Vichy). There was also an awful row made in France in the 19th Century about trademarking the "Sabatier" name, to the point where over 20 brand names using some sort of "Sabatier" label were at one time or another in production and sale, each named line produced by a different knife maker or company.
Nowadays, there are 3 companies which are considered to have historical roots to the Sabatier name - Sabatier K, Thiers Issard and Mexeur et Cie - which have or recently had their product lines available in the United States. There is also at least one "Sabatier" brand sold in the USA, imported by an American company, with knives made in China.
For the real thing (i.e., made in France), consider the carbon-steel lines as your first priority. None of the stainless steel french knives are particularly distinguishable from other stainless steel knives. It's the carbon steel knives which really sparkle in the culinary action.
"Sabatier-K" knives are available both directly from France (http://www.sabatier-shop.com/ ) and from an outlet store in South Carolina ( http://www.sabatieroutlet.com/ ), You can also find Sabatier-K knives from other retailers, including Amazon.com and China Fair Inc
Carbon steel "Thiers-Issard" knives are mostly available through "The Best Things" ( http://www.thebestthings.com/ ).
Both the Sabatier-K direct site and The Best Things site have offerings of "historical" knives, where there are knives made from knife blanks which were forged decades ago.
Mexeur et Cie used to be carried by Sur La Table, but I don't know if it will return there.
As for the Chinese-made Sabatiers, they are all stainless steel - and sold in sets of 15 or 13 knives (with knife blocks as part of the sets) for $40 and $60. Make your own impression from that price point as to the quality -
