How bad do you need them? If it’s an optional situation$30.00 is prolly too much. If you need them and choose to fly without them because of the price, $30.00 might seem a little cheap after paying for repairs from the botched landing without the gear.
Look at it like a slipping transmission. $1,500.00 to repair it now seems like a lot of money, but it’s a lot less than the $5,000.00 you’ll spend when it completely fails.
