Hold onto your money and invest in something that is gear driven...no belt...such as 301 or 301A...I have both and they are classic looking and sew like a dream and purr...
They are the big sis to the featherweight which weighs 11 lbs and the 301 or 301A 14 lbs...Trust me the 99 is like lead and you'll regret it...And they can be picked up for much less even on ebay...
