I've stayed at 2 hotels in the Meiringen area.
Hotel Baer right in Meiringen and Hotel Gletscherblick up above Meiringen in Goldern. There's a cable car from Meiringen to take you up to the Hasliberg. Both are 2-3 star and both include breakfast (or did last time). The half board is excellent value at Hotel Gletscherblick. Your budget seems a bit low though for Swiss hotels.
