Prices range from $29.99 for a used digital-display model up to $129.99 for a brand-new touchscreen unit. The $29.99 used listing is the cheapest but lacks the color touchscreen. Mid-range options around $47–$50 offer color displays in used or tested condition, striking a good balance. The [new touchscreen model at $90](product:206300636032) stands out as strong value, undercutting the $129.99 new listing while offering the same 7-day programmable features. For those wanting humidity control, the [humidity-compatible new unit at $99](product:306989044651) is worth the small premium.
