The price seems fine.
One advantage the original Air has over the Air 2 and the Air 2S - and most other Mavics apart from the Mini series - weight!
If weighs 430 grams - in the 250 to 500 gram bracket. This means that with the appropriate qualification you can fly a lot closer to people and objects than with heavier aircraft - all the Mavics.
Membership of FPVUK - recommended for the included 5 million public liability insurance - gives you Article 16 Authorisation after a simple test. and costs 20 quid total. It allows flying to within 30 metres in urban and rural settings
Completion of an A2 certificate of competence, costs between 59 and 159 quid depending on which school you sign to and how you wish to learn - confers even further privileges - close up to people in all environments. And you get to learn a lot about drone flying!
OK, I’ve simplified. the scenarios but the gist is that the Air has some considerable benefits over many of its brothers until the new C marked drones become available - and don’t wait up for that,
TL:DR - Go for it, it’s a good package
