I've had the 98-TLQ (can still get new on Ebay) for about 3-4 years and just bought the 2000. I use the 2000 on my frame and 98 to piece. Honestly I run my full speed when I piece so the speed control was not worth the extra $100 to me. These babies will sew till they drop dead. I have never had any problems but I clean every use and oil every other use. If you like the speed control I'd say get the 2010 but why buy a machine that sews 1600 spm then slow it down - LOL
