The 'old model' hand-held belt sander from HF is a beast (the old orange one with the fixed handle). I've abused mine for over 5 years now and its still kicking.
And the 'Heavy Duty Flexible Shaft Grinder' is probably one of the best 'Dremel' type tools you can buy. You can spend $200 for a 'name brand' at Wood Craft or Amazon.. or $50 at HF.
