The Trek T2000 fork is actually quite nice. Not the lightest around, but both lighter and stronger than a Wound-Up tandem fork. The AL steerer is internally reinforced with a short steel insert at the crown, specifically for tandem use. 385 A-C, 50 mm rake; Trek part number 270946; MSRP = $250, but you might be able to talk your dealer into a lower price when they special order it for you.
Our family has two tandems made for long/standard reach calipers. I like 'em a lot. Note, however, that the QR may not open wide enough to permit passage of a fully-inflated 35c tire. Depends, I suppose, on rim width. Our bikes have relatively narrow rims (Bontrager on one and Mavic CXP 30 on the other), and I can just slip an inflated 28 c through.
Good Luck - Have Fun,
