There is plenty of them around. The problem is, most of them are "vintage" and thus fairly pricey.
The Sound Workshop 242 is a classic stereo spring reverb, a bit like the Klark Teknik DN 50 (which is also stereo). Both are 19" rackmounts. Fostex, D&R, Tapco, Quad/Eight, Masterroom, Vesta Fire, Furman, and Korg also made rackmounts.
The Great British Spring is a stereo device but fairly awkward to carry around (let alone place in the studio). Shipping one of these could be a real challenge.
The king of springs would be the AKG BX-20 but this one has become extremely expensive recently, as well as its smaller siblings, the BX-25(E), BX-15, or BX-10. I would not spend a fortune on a BX-5. Too limited for the price it fetches.
For guitar and instant Dick Dale the Lafayette Reverb is interesting (marketed under different brand names), as well as the Schaller Reverb. These two are mono.
Vermona RetroVerb is one of the more contemporary (and affordable) offerings. Ekdahl Moisturizer probably is a bit too hip and correspondingly more expensive.
My personal favourite would be a BBD echo, combined with a spring reverb (e. g. Evans/Electra EP-250). This, or a Roland RE-201/301/501/555. Sweet tone.
