Probably the most widely used aquastat in the market and most reliable would be the A-419 from Jonson controls, you can get it at any plumbing supply house for around $65.00, it is adjustable to within 1 degree, easy to wire, multple functions, available in 24 volt ac or 120 volt ac, if you use the 120 volt there will be no need for any relay, you should however put a 3/4 inch port into the boiler for the well to accept the temp probe, well is not supplied with the aquastat but the probe is.
