Can I compare prices of overlock sewing machines across different online stores?

I visited a sewing machine supplier to ask about overlock sewing machines two days ago. I wanted something affordable because prices can vary a lot and I did not want to overpay without checking other options first. I also wanted a machine that still performs reliably without creating stitching problems later. But when I checked the machines there I felt confused. Some overlockers looked simple and budget friendly but the build quality did not feel strong. Some advanced models looked durable with better stitch options but the prices were much higher than expected. Some sellers kept saying their prices are the best available but I had no way to compare them properly. I could not trust them. I could not decide confidently.

Then I visited another supplier in the same area. Some companies explained that comparing prices across different sellers is important because each supplier includes different things like accessories warranty or delivery costs. Some machines looked cheaper at first but did not include essential parts while others seemed expensive but offered better value overall. Some still gave mixed answers when I asked about hidden charges and long term costs. I remembered one time when I bought equipment because the price looked low but later I realized other sellers were offering better value for slightly higher prices.

To check more variety and options while scrolling online platforms like Alibaba I found many overlock sewing machines listed by different suppliers with price comparisons and customer reviews. But now I keep wondering if choosing the lowest price is really the best strategy or if looking at overall value and reliability makes a bigger difference in the long run?
