Keeping this as simple and inexpensive as possible, while adhering to your perfectly reasonable criteria, I think there are basically three ways to go:
1. Get a mountain-specific 10 speed derailleur, to work with all of the other parts you already have. They're not especially pretty compared to 105 stuff, but they're not nearly as ugly as they were a few years ago. They do come in silver, which helps a lot: http://www.nashbar.com/bikes/Product_10053_10052_577269_-1___204714 (verify that this is Dynasys, but I can't imagine why it wouldn't be. It's mountain-specific.) 2. Get rid of the 10 speed trigger shifters you already have, and replace them with a 9 speed version PLUS a 9 speed cassette PLUS a 9 speed chain. Technically, you probably don't need a new chain, but the 9 speed is theoretically more durable than the 10, and cheaper too. Mid-range 9-speed trigger shifters are still available new, but they probably aren't any nicer looking than the 10-speed ones you just got: http://www.nashbar.com/bikes/Product_10053_10052_501280_-1___204723 3. Look for some older-but-nicer looking 9 speed trigger shifters on Ebay or something. Probably easier to find in silver. As above, this would require a new cassette and chain. Integrated: http://www.ebay.com/itm/Shimano-XT-ST-M750-MTB-Shifter-Brake-Lever-9-Speed-Silver-/371376531172 non-integrated: http://www.ebay.com/itm/SHIMANO-ALIVIO-SL-M4000-3-x-9-Speed-Shifters-MTB-Road-Bike-Pair-Front-Rear-NEW-/131565742740 Some other thoughts: - Shimano trigger shifters are probably one of the few component areas where the higher end series is worth the extra money. Ratchets and pawls are often metal versus plastic, and hold up better. (So I hear.... I have experience with exactly two bikes with trigger shifters, only because they came that way.) - Just my opinion, but twist shifters are the worst possible option. They require letting go of the handlebar and contorting your wrist in the most awkward manner, if you need to shift through several gears at once - often when you least want to let go.
