My understanding is that the earlier Boss pedals were made by Maxon, which of course now sells under its own name. Allegedly these were better than the subsequent Boss pedals, but I've never done a side by side. Be aware that if you are using a power supply for your pedals, the early Boss pedals are powered differently than the current standard arrangement. From the Analogman site:
Many old Boss pedals were designed for an unregulated ACA power supply. The PSA will not have enough voltage to work with them. So check your pedal, they originally had a sticker on them telling you which power supply type to use. If it says PSA then any regulated power supply (Dunlop, Ibanez, etc) will work. But if it says ACA, then you need to get a boss ACA (ACA120 in the USA) power supply.
You can buy appropriate power supplies from companies like Analogman and some power supplies, like the Voodoo Lab Pedal Power will power these older Boss pedals.
Edit: FWIW, I have a CE-2 (Chorus) and a CS-2 (Compressor) pedal and they are both very decent. The CS-2 has generally been replaced by my Keeley comp, but it's still a decent comp pedal. I also have some of the recent Maxon reissue pedals, an FL301 Flanger, Phase Tone Phaser and a Compressor. Decent no frills pedals (and I got them cheap).
