Mike, the Teres has no dust cover. If you want to keep dust off, you have to cover it with a light cloth of silk or nylon, or something like that.
The DL103R is not imported into the US. I got mine from a member named "Martin". You can email him through the Audiogon system. He is a dealer in Singapore. He has very good prices on the DL103R($230). He is a reliable person to deal with. Mine arrived 10 days after order, and he takes Paypal too. He puts ads on the Audiogon classified for DL103R from time to time.
The DL103 and DL103R are from the same family of cartridges. They have very low compliance(5cu) and are not suitable for unipivot arms at all. The R model has 99.9999% copper coils and a slightly lower output(.27mv). It tracks better, and sounds way better. For sure worth the extra $80. I have had both on my system recently and compared them back-to-back. The 103R is a full step better than the regular 103. Either one of them is extremely good sounding for the money, and I don't think you'll find any other cartridge near the money that can touch it. But the 103R is better and worth it if you can get it.
