I've had Michelin XZX 165R15 tyres on my beetle for a while now and driving daily I've found them to be really good tyres.
Next set I'll be getting are the Michelin XAS tyres in 155R15
There are cheaper alternatives to the Michelin classic range, but they do not have the same look as the Michelins, which are old moulds with modern compounds, with the exception of Vredestein.
Depends what size tyre you're after and what rims they are to go on, but assuming stock rims and 165R15 below are some options.

Hankook Optimo K715 - $
Maxxis MA701 - $
Vredestein Sprint Classic - $$
Michelin XZX - $$
Michelin XAS - $$$
Pirelli Cinturato - $$$
Avon CR6ZZ - $$$$ (Classic R-spec tyre)
In terms of fitting tyres, I've usually just taken my wheels to the nearest tyre dealer to be fit, but when I have left the car there hasn't been an issue; perhaps you could take the hubcaps off before heading there.
As an alternative vendor these guys in the UK have a really good range of tyres and are competitive to Aus pricing IMHO
