Have made a fair number of buys on ALI with satisfaction.
Great savings on smaller items that are shipped free with the only downside being the wait time.
Naturally quality is always the concern but then depending an the item it probably is what you'd buy locally at 4-20 times the local store.
Must admit that larger items like tractors are very interesting to compare with local pricing however parts would be the major concern.
Heck I have seen 40hp 4 x 4 with FEL in the $6-$10 k range shipped for $800. to nearest port. Not shabby and tempting.
Same for parts, (if you can cross reference) , like WOW.
Recently was blown away on hydraulic pump prices.
Have bought back up camera systems and other electronics all with satisfaction.
So far all has arrived duty and tax free as well.
Just takes patience and or planning ahead.
