I'd suggest the system recovery method for $30 myself. It might save you from going crazy trying to find the correct drivers. Additionally if there was any bundleware that you liked you would get that back as well with the recovery.
*One work around to buying a recovery disc or media would be if you had a friend with same exact make/model laptop the recovery media is the same for that model for everyone who has that model and so you could use your key with anyone elses like make/model recovery media. The recovery media can be created for free from a healthy computer. Its usually in a folder with the manufacturer name such as HP, Dell, Acer, Toshiba, etc in which there is an option for System Recovery Media Creation. Some systems have a counter and only allow this to be created once or twice, other systems dont care how many times you make recovery sets.
