geek,
Taillift is a fairly new player in the US market. The trucks are made in Taiwan and they are limited in terms of specifications and models. Over the years there have been several companies from Taiwan that have made attempts at coming into the US market but have failed due to poor parts support and lack of good quality dealer representation.
If I were you I would stick with a known brand like Yale, Hyster, Nissan or Cat. Get proposals from all of them and then look at the local dealer for each brand in terms of service capapbilities and reputation. Ask each one to tell you about the total cost of ownership for their trucks. Remember, the real cost of owning and running a lift truck is not in the acquisition price but rather in the cost of operating it and maintaining it. Make sure you consider all of those aspects and pick the brand that you feel is best equipped to deliver the lowest cost of ownership/operations to your company.
