Can I trust an independent garage to replace a DPF?

I keep needing to get the garage to do DPF regen on my Mazda 5. It has done 60,000 mostly city miles and I think it's time to get the DPF replaced. However, the main dealer has quoted over £2000 for the work and possibly up to £3500 if all sensors need replacing.

A recommended independent quotes £1200, for a 'dealer spec.' DPF that they say comes from the same factory as the main dealer part. Is the DPF a particularly complex part that only the main dealer should do?

This is an issue with this engine in Mazda 3s, 5s and 6s. The problem can be that the ECU introduces too much diesel to the engine to 'actively' regenerate the DPF and this both contaminates raises the level of oil in the sump. So you really need an expert in solving this problem rather than a garage that just replaces the DPF.
