beltbuckles

so i design handbags and i think i could use a better machine for the lining inside the purse.. would this machine be good for stitching.. right now i use a home machine with no table and it is tough at times to do something cleanly.. would this be a big upgrade or is there some much better>"? (its the blue model singer 20u)

so i was making handles on a purse (sewing kinda like 2 belts on top of each other sewn together).. using a 1/8 inch seam guide walking foot on my consew227.. but the problem is that even though i go kinda slow, it always gets crooked and goes off on the bottom leather.. any tips for this.. maybe a left toe and swing guide???? help??

so i let the machine sit for a hour before "surgury",, i just tried it now.. and i can go forward fine,, but when i turn the wheel in reverse,, it can't do a full rotation..it gets stuck on that "triangle thing" by the bobbin case

so i was sewing just fine, and the machine was jamming up with thread here and there so i would clean it out.. then all of a sudden, i hear a loud squeech noise... ???? i take a closer look .. i removed some stuff out of the way (throat plate) and stuff by to bobbin area to see what happened??? it looks like the traigle part of the bobbin case in the hook area hit that little "arm" looking thing and it won't turn one full rotation.. either forward or backward... please help!! it makes a loud squeech each time?!?

thank you all very much for your responses.. -i did find a few more machines.. a singer 29d71 http://newyork.craigslist.org/brk/atq/5967018439.html -and a juki246 http://southjersey.craigslist.org/bfs/5921889507.html for handbags.. are they worth pursing? should i just go for to the singer 153 (it needed a needle to be able to test it out) plus i never threaded one before and the guy had little knowledge of the machine

so i am looking into getting a machine that is for sewing leather handbags. i live in NJ. I have very little knowledge on this subject. i guess a cylinder arm, walking foot ?? anyway, i did some searching nearby, and i found a singer 153w103 machine. the owner didn't know much about it.. and it didn't have a needle so i could not test it out... they wanted $800 but the price was negotiable. i did find an adler 105 that a shoe place was selling. they wanted to upgrade. i wonder if the one they are selling is junk or still usefull? i don't really know enough to determine what to look for when buying used... i could buy new, but i strongly prefer to buy used if possible to save money.. i heard cobra 4, pfaff 335 ect.. are good but finding a used one is really tough
