Mostly on the mirror size you wish to grind, and the prices of the local market. In the US, telpe mirrors are the cheapest. A decent 6" (150 mm) mirror can be bought for under 100. In Europe, prices are usually twice, if not three times that. In some countries telpe mirrors are unavailable, so they need to be imported, at high shipping, customs, and tax cost.
