Presuming that you don't want to replace the entire drivetrain, a new-or-used pair of 10-speed Campagnolo ERGO shifters is actually the least expensive option; and, you can directly substitute a pair of pre-2007, Campagnolo 10-speed VELOCE shifters that you will find on eBay for between $80-to-$120 (the price range varies ...).
You do NOT want a 10-speed VELOCE shifter that has a 'QS' on the left shifter ... unless you are only going to use the shifters with a DOUBLE crankset.
You do want 10-speed ERGO shifters (no 'QS'😉 if you are going to use the shifters with a TRIPLE crankset.
If you feel you must maintain Shimano-only, you can probably find a new pair of 8-speed SORA shifters on eBay, too.
There are other options ... including a used pair of rare 8-speed Shimano 105 shifters or some 9-speed Shimano shifters which are triple compatible (only some are) if you're willing to pay more & do some minor fiddling with the rear derailleur cable's anchoring position.
8-speed Shimano bar end & downtube shifters are another option.
