To add to Drivers comments.
I used an ACE yoke until I replaced it with a OEM yoke and column from a real B737 which was converted for FS use. The yoke was quite good for a reproduction item but paled when compared to the real item.
ACE initially replied to all e-mails and the payment was very easy.
I waited close to 5 months - after full payment, for the yoke to be made and then shipped to Australia. During this time e-mails from ACE were very sporadic and I had to push for a delivery status - there were all sorts of plausible excuses to possible delays......
On receipt of the yoke, the clipboard was missing in addition to some wires that were not correctly installed. I repaired the wiring myself.
I contacted ACE concerning the clipboard several times over the next 3 months - the e-mails were not returned, until I mentioned that I was going to post a negative review on a forum - ACE then replied indicating a clipboard had been dispatched. I asked for tracking data but this was not supplied. Nothing turned up and I contacted ACE again to be told the clipboard would be sent to me in another consignment that was due to leave for Australia - this was to save postage.
Long story short, the clipboard arrived ~3 months later with a yoke for another Australian client in another state! I had to contact the client directly to arrange shipping to my state. I complained to ACE and they sent the internal shipping funds to me.
Needless to say I would NEVER deal with ACE again. For some reason ACE does not reply to e-mails. Furthermore, the company is not prompt in anything they do - other than in taking your payment.
Unfortunately this scenario is repeated time and time again with ACE and other unreliable re-sellers. DEAL ONLY WITH RELIABLE VENDORS.
