So i bought new sewing machine at Spot light. The cheapest one ka $199.About 5,800 baht ka. Brother BM-2600 I think it's OK ka. Easy to use. But a bit smaller than my Janome
The sale lady told me this machine function is very simple. "Why don't you buy the better one." So i asked her is this machine break easily??? The answers is :Not really: just " What ever you pay, what ever you get"
