freezing and need steam boiler help!

kml

Greetings, I am researching and getting crazy stratospheric quotes on replacing a 75,000 BTU steam boiler. Can you advise on 1) brand and any add-ons 2) any contractors that would not insult us with an absurd mark-up, what we should expect? Can you help us? We are located in SF.We have been suggested a Peerless and a Weil Mclain, which is better?  Standing pilot or spark ignition? Is ther another brand we shoudl consider? Don't need to have a "Cadillac", just a "Toyota" steam boilerout situations:<ol><li>1200sq foot condo, floor above the garage</li><li>4 radiators (one pipe- no return): 1- 8 tube radiator, 2- 4 tube and 1- 5 tube</li><li>the backflow apparatus in tact</li><li>piping all there: supply, return, outflow venting...</li><li>gas there</li><li>electric there (maybe need a little thermo adjust)</li></ol>Thanks a million!
