igorportugal:What I meant is if local company does brand X and there is no other company around that does that brand then you are stuck with that company even if you end up not liking there work, people or pricing later down the track.
I am not sure I follow the logic here.
If you don't like the reseller, you can always go direct to the manufacturer regardless of how many people represent the company - we have parallel importing laws, so this is well and truly protected by legislation.
If you don't like the manufacturer, then you are really in the same boat whoever the manufacturer is.
A manufacture or distributor does not usually come out to your site and do any work on your system and they also don't usually sell direct to the end user. If there is no other local company/resellers in your area that do the system you have they won't have any one else nearby to recommend either.
even if it's an open source product if your not able to look after it yourself it would be good to know there are multiple local people/companies that can look after it for you before you get it installed. (now do you follow?)
