I don't know anything about that machine. But, if you have set a budget, stick to it. Remember, the bottom line for every business is to make money.
If this shop is really pushing a particular machine, step back and look at their motivation. If it is money, rather than your best interest, I would consider looking at another store if you can.
Otherwise, there is no shame in telling the sales person my budget is XXX total and I won't go over it. They should have no problem helping you find something appropriate in your price range.
And, always try before you buy!
