Thirded. Even switching to a 2 years old used T every other year is still cheaper than spending 2k just to get what's currently high end and hope it lasts you 6+ years.

You get them decently refurbished on ebay as they are popular leasing models for companies which switch them out more or less on a fixed schedule. If you're lucky you get one that was sitting in a docking station for two years and is almost pristine, just the battery destroyed because it was on AC power uninterrupted.
