Janome Computerized Sewing Machine

Recommended sewing machines?
Right now I have a Janome Sew Petite that I use for sewing everything. The bobbin thread gets messed up every 2 – 10 stitches, and I have to stop and fix it, making it impossible to sew with the bobbin plate cover on.
So, i decided that I really need a new machine. I do not need a lot of different stitches, I usually use the straight stitches and the zig zag stitches. I use it mostly for sewing clothes. I was wondering if anyone could recommend a sewing machine for me? I don’t want something computerized or really expensive. I’m planning on spending $100 – $200. I just need something that won’t break down on me and will last me a while. I do not need something super complex.
Thank you in advance.
The sewing machine I’ve been recommending to people who want a “basic model” machine is the Brother that was developed for Project Runway. It’s a $400 electronic machine. It’s performance is almost as good as that of machines costing 4 times as much and it’s easier to use. It’s available at Sears: http://www.sears.com/shc/s/p_10153_12605_02094040000P?vName=Appliances&cName=Sewing&GarmentCare&sName=Computerized&sid=IDx20070921x00003c&srccode=cii_10043468&cpncode=24-93572046-2 , Circuit City: http://www.circuitcity.com/applications/searchtools/item-details.asp?EdpNo=5302472&SRCCODE=BIZCC&cm_mmc_o=2mHCjCPbOyzfwCjCVqHCjCdwwp&cpncode=18-64051563-2, and J&R: http://www.jr.com/brother/pe/BRT_PC210PWR/ .
If you really and truly want a super-good sewing machine that’s not electronic and is inexpensive, you can’t beat the Brother xl-2600i: http://www.jr.com/brother/pe/BRT_XL2600I/ .
