If you are on that tight a budget, I would take a look at the price of vinyl. What will 100 records cost you? Also, as someone that grew up with vinyl, you have to work for the music. Vinyl needs to be cleaned and handled. It takes up a lot of space and is really heavy if you move to a new place. It is easily damaged. If you use cd you take for granted the ease with which you can skip around a disc, with vinyl this is not really part of the deal, short of getting up and physically moving the needle. Do you want to get into vinyl, or do you want to experience the mystique of vinyl?
I would add up the cost of 100 albums, a player, a cartridge, and the time you will spend getting there.........and think of the caliber of speakers you could buy with that money.
You could not pay me to go back to vinyl.
