recommendation for Metro 3 cylinder piston rings?

[metrojunkie]

looking for recommendations on brand model best part for replacement Rings compression and oil complete set for my 3 cylinder naturally aspirated Metro I'm looking for a good high quality ring for efficiency but I don't want to spend a fortune so I'm looking for a good balance so let me hear what you think and where I can get them thanks and have a great weekend

Any name brand molybdenum plasma coated rings. File fit are best.
Do not buy total-seal.

none of my local Parts houses can seem to find Molly coated rings.
any recommendations for an online supplier I see there's a huge variation in price and I imagine a huge variation in quality of service so any recommendations for an online parts house that I can get moly-coated rings at a decent price for my metro

Thanks
