What are pros and cons of a single spring vs double spring motor? I've read that there has been also a triple spring....
Yes, Edison marketed a couple of Phonographs in the 1896-1911 period which were equipped with a triple-mainspring motor known as the "Triton." Columbia marketed several machines (cylinder and disc) with 4-mainspring motors, and many of the larger post-1917 Victrolas are equipped with 4-mainspring motors.

Length of play?
Typically, the more mainsprings in a motor, the longer it will play on a single winding. Columbia marketed a very popular Graphophone from 1897-1907 (The Type B, or "Eagle) with two mainsprings, but they were so small that some machines with a single, larger mainspring could play longer on a single winding.

Having multiple mainsprings means that each mainspring is sharing the work with the other mainspring(s), but the disadvantage of this is that if one mainspring breaks, the motor will not function.
ymg200 wrote:Collectors value?
Multiple-mainspring motors are usually found in upper-end machines, so the collector value may be higher, but not so much because of the mainsprings. Many earlier machines with single mainsprings are worth far more than nicely-playing multi-mainspring Victrolas of 20 years later. Don't buy a machine based on the number of mainsprings. Also, decide if you want a machine to use as a daily player, or a rare specimen. Many of us have scarce talking machines worth many thousands of dollars that don't play well - - and never did. Meanwhile, a common Victrola worth perhaps $150-$200 will play nicely and provide utility that the "shelf queens" cannot.

Mainsprings can and do break. Metal fatigue affects these parts over time. Luckily, new mainsprings are readily available at reasonable prices, and the parts suppliers will even install them in your spring barrels if you wish.

I wouldn't recommend a prospective collector to go out and buy a rare machine. First, decide what you like: musically and visually; and set a budget for your first purchase.
For cylinder machines, start with a common model such as an Edison Standard Model D (it plays both 2-minute and 4-minute cylinder records with the proper reproducers). If you don't care about the external horn of the Standard, and prefer fox-trots to earlier popular music, get an Edison Amberola 30.
For disc machines, common models are the Victrolas VI, IX, XI, XIV, and XVI (I left out the IV because it has a smallish single mainspring and you'll spend a lot of time winding it if you enjoy playing records). These are in ascending order of original price and features. They all play 78 rpm records, which are in plentiful supply and are often given away free by collectors.
These are just my suggestions, and others will have their own perspectives. In short, start simple and buy only what you like. Don't be in a hurry, and hopefully get some exposure to some different machines before taking the plunge.
Good luck!
